Founded in 1992, SunPower is a solar company that prides itself on delivering reliable energy and long-term peace of mind for homeowners and businesses. The company is a pioneer in the industry and currently holds more than 750 patents for solar technology.
SunPower is known for manufacturing top-quality and high-efficiency solar panels that generate more power than conventional solar technologies. The company has a uniquely attractive, all-black appearance for itself and offers a few different options to help both residential and commercial consumers get started with renewable energy. SunPower outsources most, if not all, of its projects to third-party solar installers.

SunPower offers three different payment options for customers to choose from: solar leasing, purchasing with cash, and financing with a loan.
With the lease option, SunPower Capital owns the system and the customer rents the system from the company, requiring monthly payments. The lease comes with a 20-year performance guarantee, as well as easy options in case the customer needs to transfer the lease.
SunPower also offers outright purchase and financing options for customers interested in the tax credits and other incentives that come along with solar power ownership. Loan terms for solar systems typically range from 5 to 20 years and do not have any prepayment penalties attached.
The cost of a SunPower solar system ultimately depends on several factors, including current energy usage, available amount of unshaded roof space, the local utility’s net metering policy, and other factors. The easiest way to figure out exactly how much solar will cost you is to obtain a free quote from SunPower.
SunPower is on the cutting edge of solar technology and excels when it comes to innovation, design, and production of solar equipment, so customers can be confident that they will have high quality products on their homes.
In fact, SunPower makes the highest efficiency solar panels you can buy for your roof in today's market, and the company's solar cells are made of anti-reflective glass and coated with anti-reflective coating to ensure that they capture as much sunlight as possible.
SunPower's X-Series solar panels excel in terms of power generation and deliver 44 percent more energy per watt than competitive products. This means that SunPower can provide more clean power for its customers' homes with fewer solar panels.
SunPower panels also boast 75 percent more energy per watt than conventional solar panels, meaning that an investment in a SunPower system will ultimately pay off more in the long run.
Additonally, SunPower panels maintain their energy production much better than conventional panels in partly-shaded conditions, making them a better rooftop solar option for customers who live in a cloudy region or a relatively shaded area.
In addition to being highly efficient, SunPower's panels are uniquely attractive and aesthetically pleasing. While many other companies in the solar industry offer traditional blue photovoltaic panels, SunPower's panels are all black, which helps them to blend in better with the rooftop on many houses.
SunPower's panels are compatible with the Freedom CPAP Battery produced by Battery Power Solutions. When a SunPower module is installed along with this battery, customers will still have access to electricity in the event of a power outage.
Online monitoring is extremely important for customers who want to see what the panels on their roof are producing and ensure that everything is up to par.
SunPower offers a helpful, convenient app for customers to do just that. The app provides important system information such as power output, savings, energy usage over time, and environmental effects.
There is also a consumption monitoring kit that provides more information than the app for customers who would like a more in-depth way to monitor their system. The consumption monitoring kit is installed by the dealer, but may not be compatible with all homes.
SunPower offers multiple warranties to protect its customers' solar energy systems, including a 25-year product warranty, which covers the equipment itself, and a 25-year workmanship warranty, which covers the labor and installation. The clean energy company also offers a 25-year performance warranty, which covers the customer in the event that their solar modules underperform in terms of electricity production and output.
Many customers may be interested in obtaining a SunPower module through a Power Purchase Agreement (PPA) because this payment method typically includes some kind of $0 down option, which eliminates a barrier to entry for them to go solar.
Unfortunately, SunPower only offers PPAs to commercial customers, so consumers who are interested in a PPA for their home solar system will not have much luck with this company.
SunPower is performing installations itself in select areas of California; however, SunPower panels are available in the following 18 states through a network of dealers:
The dealer you choose will end up being your installer and customer care center for the life of the solar PV panels, which creates a bit of confusion as to who should be contacted (the dealer or SunPower) in the event that any issues occur.
Many users on our site have provided negative feedback in regards to SunPower's customer service.
Common complaints include difficulty to reach a representative, company failure to return phone calls, slow response time, and inability to resolve issues.

Performance of the panels are good and a received defective microinverter notification and replacement.
Very well built panels, terrible monitoring site. We have had these panels for two years. It is a 10kW that is delivering an average of 12mW/yr. We track our performance with a SolarLog which is needed to ensure that our SRECs are correct. The SunPower monitoring site worked poorly at first and now mostly not at all. Example, today we are currently running at 9.8kW. I know this from the SolarLog site. The SunPower realtime shows 0.2kW for production at the same time. We were told that we could track power productions vs power used, total fabrication until they hire someone to repair the site. We invested a lot to make this 1978 hummer of a house into a hybrid and a good monitoring system would go a long way to keeping it efficient. Too bad we didn't get that with the SumPower panels. Our installer, BluSel, is fantastic. They have tried everything possible to be sure the install didn't have any issues. This rests solely on SunPower and their neglect of this aspect of their business. I have 45 years of experience as a vender to the solar panel industry, these are good panels. Too bad after install support is non-existent from the factory
a Sub contractor installed my panels , Did a terrible job contacted SunPower They immediately sent a reprehensive out and corrected the problem and did a prefect job I would Highly recommend SunPower but not a Sub contractor
They were responsive to our needs and do high quality work.
Delivered as promised on time after 1 year no Edison bills.
verry nice people and a 25 year gaurantee made it easy to deal with. I will use them again
Quality of the product, installation and customer service.
I have had the panels for a year and have no issues. I am producing more electricity than I use.
corrected the installation issue fast and less equipment installed in my house.
There are too many times my app doesn't give me my info because the system is not functioning properly. If I delete the app and start over that usually gives me access again. Very awkward to do all the time.
Right now I'm being generous. My system is not still 100% functional
Sunpower has made good on all their promises, and they seem to be getting even stronger, while another company tried to 'steal' me away with underhanded practices and deceit.
Our panels are working well and the installation was relatively painless.
Best Solar Panels & Price, Their people make it effortless.
Solar production was great even on overcast days.
They have been very forthright. It did take quiet a long time to get it installed.
did a professional job in a timely manner
I like SunPower panels for efficiency, appearance and reliability.
Best efficiency. System is working without any problems.
Great All Around
Excellent product and customer service all the way around.
Poor online monitoring tool. It's mostly not functional. Useless.
They installed my solar system on time without issue. They kept me informed every step of the installation. My garage opener didn't work after the instalation and SunPower paid to repair it.
They have all the answers to my questions and they were on time.

Highest panel wattage in the industry, highest quality inverters and an excellent warranty
The panels are the best, they perform as advertised
installed & online quickly. Sleek, efficient panels. Good app for tracking power usage.
The whole process was stress free. We were informed every step of the way.
Great service, from sales to installation.
Only solar panels my installer would use; 25 year warranty.
I chose SunPower for my residential solar system because they make long-lasting, high-quality panels with the best efficiency rating in the industry. I also like their integrated approach to system design, in which they manufacture and use all of their own components.
Their representatives, follow-ups and prompt responses to questions are admirable.
My chat experience yesterday was terrible. I started 6th in line and it took hours to get through.
personnel very professional, knowledgeable, excellent follow up and support.
Great product, looks better than other solar systems in the neighborhood.
I have had my solar panels for 6 years and my solar panels stopped working. I rent my panels from SunPower who provides all the maintenance and operation on them. SunPower sent out a third party contractor who diagnosed the problem as a defective power inverter. The contractor said that it should take should take about two weeks to get the parts and a day to replace the inverter. It has been three months and my power inverter still has not been repaired. I have called both SunPower and the third party contractor numerous times to get a status update and each one blames the other for the delay. UPDATE: Parts were finally received by the contractor to make the repairs (after more than two months since the contractor informed SunPower of the problem). However, I strongly believe that if I had not made repeated calls to SunPower concerning my problem, nothing would have been done.

Hello Mr. Gilman, I’m sorry to hear that your expectations have not been met. We'd really like to look into this further. Please expect a call from an Executive Support Specialist to discuss your concerns in detail and provide additional assistance. We appreciate your business and truly value your feedback
Great product, almost great service. We had to call them a couple of times to get an update on our project. I felt like if we had not done that, the install would have taken longer. They were very receptive to our concerns and made it right immediately. I would work with them again.
Top of the line panels that are very advanced technology wise
They were very easy to work, upfront about costs and timelines, they handled all the permits and coordination with the electrical company, as well as help me apply for a State grant
